Topic 1, Web-based Solution
Background
You are developing a web-based solution that students and teachers can use to
collaborate on written assignments. Teachers can also use the solution to detect potential
plagiarism, and they can manage assignments and data by using locally accessible
network shares.
Business Requirements
The solution consists of three parts: a website where students work on assignments and
where teachers view and grade assignments, the plagiarism detection service, and a
connector service to manage data by using a network share.
The system availability agreement states that operating hours are weekdays between
midnight on Sunday and midnight on Friday.
Plagiarism Service
The plagiarism detection portion of the solution compares a new work against a repository
of existing works. The initial dataset contains a large database of existing works. Teachers
upload additional works. In addition, the service itself searches for other works and adds
those works to the repository.
Technical Requirements
Website
The website for the solution must run on an Azure web role.
Plagiarism Service
The plagiarism detection service runs on an Azure worker role. The computation uses a
random number generator. Certain values can result in an infinite loop, so if a particular
work item takes longer than one hour to process, other instances of the service must be
able to process the work item. The Azure worker role must fully utilize all available CPU
cores. Computation results are cached in local storage resources to reduce computation
time.
Repository of Existing Works
The plagiarism detection service works by comparing student submissions against a
repository of existing works by using a custom matching algorithm. The master copies of
the works are stored in Azure blob storage. A daily process synchronizes files between
blob storage and a file share on a virtual machine (VM). As part of this synchronization, the
ExistingWorkRepository object adds the files to Azure Cache to improve the display
performance of the website. If a student's submission is overdue, the Late property is set to
the number of days that the work is overdue. Work files can be downloaded by using the
Work action of the TeacherController object
